Description

stack of 8 frames with pixinsight 1.7

DBE, multiscale processing, star reduction and noise reduction in pixinsight 1.7

this was taken from the parking lot at badger pass ski area in yosemite.

shot on kodak royal gold 1000 using a pentax K-1000 and a prime-focus 50mm, f/2 lens. scanned with a nikon ls-50. cannot remember the subexposure details, but i believe i had piggybacked the camera on a meade etx-90 (wedge mounted) with crude polar alignment. so probably a minute or so for each exposure.
